It is your responsibility to protect yourself from the sun all year long. All year long, use a hat, a shirt, or sunscreen (SPF (Sun Protection Factor) 15+) to shield yourself and others from the sun. The sun and artificial sources, such as tanning beds, both emit ultraviolet (UV) radiation, a type of non-ionizing radiation. Although it helps humans in some ways, such as by producing vitamin D, there are also potential health hazards.
UV rays from our environment:
- A sun
- Some UV radiation produced artificially include:
- Tanning tablets
- Lighting made of mercury vapour (common in gymnasiums and stadiums)
- Several of the lights are halogen, fluorescent, and incandescent.
- certain kinds of lasers
UV Ray Radiation Types
Based on their wavelengths, UV radiation is divided into three main categories: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). Though some UVB radiation does reach the earth, the majority of UV energy that does is UVA. Both UVA and UVB radiation can have a negative impact on health, although UVA has a deeper penetration rate and is more consistent year-round. Benefits
the process of making vitamin D, a necessary nutrient for human health.
Vitamin D supports the formation of bones by boosting the body’s absorption of calcium and phosphorus from meals. The World Health Organisation (WHO) advises getting in the sun for 5 to 15 minutes, two to three times per week.
- Sunscreen is applied to the face of a little child who is sporting a brimmed hat and sunglasses.
- UV rays can be warded off using sunscreen and eyewear.
- Premature aging and skin cancer are side consequences of continuous UV exposure, while sunburn is a symptom of short-term overexposure.
- If eye protection is not worn, UV exposure raises the risk of potentially blinding eye illnesses.
- UV radiation overexposure can cause major health problems, including cancer.
In the US, skin cancer is the most prevalent type of cancer. Basal cell cancer and squamous cell cancer are the two most prevalent kinds of skin cancer. As a result of these body areas being the most exposed to UV radiation, they frequently develop on the head, face, neck, hands, and arms. UV radiation exposure is the main cause of melanoma, the deadliest type of skin cancer.
UV radiation can have negative health impacts on anyone; however, the dangers are higher for those who:
- Have a sunburn or spend a lot of time in the sun.
- possess skin, hair, and eyes of light color.
- All skin types may experience an increase in skin and eye sensitivity to UV radiation when taking some oral and topical medications, such as antibiotics, birth control pills, and benzoyl peroxide treatments, as well as some cosmetics.
- a member of your family has skin cancer.
- over the age of 50.
Why you must guard your eyes
Even on foggy days, the sun shines down on you as soon as you step outside. You should shield your eyes from the ultraviolet (UV) rays of the sun when you are outside.
The macula, a structure in the rear of the eye, is harmed by one type of UV radiation called UVA rays. It makes it easier to see fine details. It is a piece of your retina, which communicates with your brain by converting light into images. Your retina can also be damaged by the sun’s blue and violet spectrum.
Another type of UV radiation known as UVB rays can harm the cornea and lens in the front of your eye. Your eye’s lens admits light, which the cornea and lens combine to concentrate on the retina.
Man-made UV rays can harm your eyes, and they can be released by welding equipment, tanning beds, and lasers.
Your eyes could suffer greater damage from wearing very dark, UV-unblocking sunglasses than from not wearing any at all. Because of the black lenses, your pupils enlarge and let in more light than they would if you were not wearing sunglasses.
Illnesses brought on by UV damage:
UV rays that reach your eyes, even for a little period, can increase your risk of developing certain disorders and diseases.
Photokeratitis: This symptom resembles an eye sunburn. It is brought on by prolonged, intense UV exposure to the eyes.
Sunlight can reflect from sand, snow, water, and ice. Watch out for light that reflects off water or the ocean. Additionally, while outside in a snowy and icy environment, you may get a kind of photokeratitis known as “snow blindness.”
These signs include:
- tears in the eyes
- a scratchy sensation in your eyes
- Intolerance of bright light
- Observing halo
The longer your eyes are exposed to UV radiation, the more severe your symptoms may get. However, the issues usually go away and do not harm your eyes permanently.
Cataracts: This condition that causes clouded eye lenses can be brought on by many years of exposure to the sun’s UV rays.
Some symptoms include:
- Dual image perception
- sensitivity to strong light
- Having trouble seeing at night
- requiring additional light to read
- vivid colors becoming faded or dingy.
Surgery is the only technique to eliminate cataracts.
Macular degeneration: Like cataracts, this condition is more prone to develop in eyes that have been exposed to UV light frequently. Genes also play a role.
There are two different forms of macular degeneration: moist and dry. It causes the macula to degenerate and causes you to lose your central vision. Wet macular degeneration always begins as the dry type, whereas dry macular degeneration is more frequent.
Macular degeneration signs and symptoms include:
- Straight lines that are twisted or wavy.
- vision difficulties within the first few minutes after entering a dark environment.
Pterygium: Reading words on a page with similar-coloured Pterygium is challenging. This development in the conjunctiva, which covers the white portion of the eye, can be brought on by UV radiation, wind, and dust. Pinguecula, a yellowish growth in your eye next to your nose, maybe the first sign, or it may develop on its own. The growth may start off modest or become so large that it impairs your vision.
Pterygium and pinguecula symptoms include:
- Red or enlarged the conjunctiva when the development increases.
- On the white of your eye, there is a yellow speck or bump.
- Your eyes may feel gritty, dry, scratchy, or burn.
Pinguecula and pterygium typically do not require therapy. Your doctor might prescribe eye drops to help your eyes feel better. If the pterygium becomes too problematic, surgery may be required to remove it.
Skin cancer around the eye area: Since the skin on your top and lower eyelids is thin, UV radiation can more easily harm them. Your risk of developing nonmelanoma skin cancers on and around your eyelids may increase as a result. Around the eyes, basal cell carcinoma is the most prevalent type of cancer, but squamous cell carcinoma can also manifest.
Melanoma is another form of skin cancer that, though uncommonly, can develop in or around the eyes. If UV rays increase the risk of eye cancer, researchers are unsure of it.
Basal cell carcinoma symptoms include:
- A bump that resembles wax or pearl
- A brown or skin-colored, flat growth that resembles a scar.
- a sore that bleeds, scabs, cures, and then returns.
- On your face, neck, and other exposed areas of your body, basal cell carcinoma typically develops.
Squamous cell cancer symptoms can include:
- Reddish, tough lump
- scaly, crusty growth that is flat.
Squamous cell carcinoma can also appear in body areas exposed to sunlight. It may develop in body regions that do not typically receive sunlight in people with darker skin.
The size, nature, depth, and location of precancerous and cancerous growths all affect how they are treated.
What to do or wear:
Only roughly half of the sun’s ultraviolet rays are blocked by baseball caps and hats with a wide brim. And although you can buy some with a specific UV-blocking substance, polarised lenses do not stop them from coming in.
Your eyes can be adequately protected by wearing sunglasses that block 99% to 100% of UVA and UVB rays. When purchasing sunglasses, keep the following in mind as well:
- Reduce visible light by 75% to 90%
- The same degree of blackness in the lenses. If the lenses vary from light to dark, the top should be the darkest and the transition should be gradual.
- Lenses that do not alter your field of vision in an unnatural way.
- lenses that are grey, enabling accurate color vision
- A frame that complements the form of your face and is close to your eyes.
- If you engage in outdoor activities or employment that could endanger your eyes, you should wear eyewear with impact-resistant lenses comprised of polycarbonate or a substance known by the brand name Trivex. To shield your face from wind and UV rays coming from the side, you should also acquire sunglasses that wrap around your face.
- Children and teenagers should also use the proper sunglasses. Up to 80% of a child’s lifetime sun exposure might occur before the age of 20.
- Avoid the sun, if possible, between the hours of 8 and 10 in the morning and 2 and 4 in the afternoon.
